Hi,I bought the stm32f401 board from aliexpress."WeAct" print is on the back.Seller's site do recommend the DFU method to program the board.But, I want to use ST-Link, so I made a simple program to control gpio port. Fusing by ST-Link seems to be good, but, the gpio is not controlled.I am familiar with STM32F10X. I did several projects using STM32F10X.I though gpio control is simple, but not.I am using newest SW4STM32 and ST-Link Utility.My program is as follow:So simple.void main(void){  /* GPIOG Peripheral clock enable */  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);  GPIO_InitTypeDef GPIO_InitStructure;  /* Configure PG6 and PG8 in output pushpull mode */  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;  GPIO_Init(GPIOA, &GPIO_I

Hello,I am trying to get data of battery in stm32cubeIDE,I have taken voltage and temperature of battery successfully but when i was trying to get current of battery, it shows value like 65535 or 65473....like a garbage value.I am reading current in milli ampere.I also checked value on bqstudio as shown below image and it is (-1103mA),negative sign because it is discharging current.But when i send the register address of current in this same bqstudio,it shows garbage value FBB2 i.e.64434 same as showing in stm32cubeIDE. I have connected load of 5ohm and battery voltage is 3.5v .Please give me any suggestion.

I am trying to do serial port communication using the standard Peripharel Lib. But Std has changed a lot compared to other versions.

Hello Everyone!I have some problem using SPI comunication between my STM32F103C8, and the angle sensor MA730.I get by separated the first 8 bit data and the second 8 bit data with de HAL_SPI_Transfer function, and looks like fine, but i get not values between 64 and 192 in the first 8 bits data. (See the video).I don't think that is a hardware problem, because i have not problem when i get values with arduino.What may be the problem?Thank you!!/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2019 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under BSD 3-Clause license, * the "License"; You may not use this file except in compliance with the * License.

Hello, Is any PC GUI tools with X-NUCLEO-NFC05A1 for function estimation easy?X-NUCLEO-NFC05A1 can be adapter with NUCLEO-F401RE MCU board, but it has no PC GUI tools to work with NFC function estimation as 3911B-Discovery board.I only saw the firmware driver available?please kindly advice. Thank you.

1) Issue is we are unable to upgrade new .dfu file in to a target board (which has STM32F767 ) with different target ID & different target name than already programmed in to our target board. (Please check image with red bottom line)We can be able to load different .dfu files (generated using DFU File Manager (v3.0.6))which has same target ID & target name (Please check image with green bottom line)We did full chip erase using STM32 ST-LINK Utility but still not able to reload different target ID in to target board. In which memory region these information regarding DFU (target ID & name etc..) gets stored, How can we erase or reprogram them? 2) What are the benefits of using custom VID, PID & version in a .dfu file in our custom target board.3) Is DFU file generation or programming method store anything in to OTP memory of STM uc.4) What are the differences between secure firmware upgrade & DFU, Is secure firmware upgrade possible using USB Host.Please comment.

HiI thinking of buying and STM32WB (P-NUCLEO-WB55 evaluation board) because of the fast ADC. I need to sample four analog signals with a rate of a few hunderd Ksps and store their values.what would roughly be the sample rate when using 4 adc inputs (8bit)?Is there any direction you can guide me to, to accomplish this? (example/ adc application note)Thanks in advance,

Hi,This is what I found in the reference manual:​Once the transfer is completed, this [NDT] register can either stay at zero (when the stream is in normal mode) or be reloaded automatically with the previously programmed value in the following cases:– when the stream is configured in circular mode.– when the stream is enabled again by setting EN bit to '1'.What I understand is, that in circular mode after each transfer the NDT register gets reloaded (which makes obviously sense).​But what happens in the following situations (for non-circular streams):Stream automatically disabled after last transfer and enabled againStream automatically disabled, then configuring other values, then enabled againStream manually disabled and then enabled again without configuring other config valuesStream manually disabled and then enabled again with configuring other config valuesStream automatically disabled, then manually disabled, then enabled againStream crashed and enabled again​I hope this questio

Hello, I'm facing a strange problem. I just bought the LRWAN2 package, connected the gateway to the network, one usb cable to power it and one usb to the st-link. I configured the packed forwarder to router.eu.thethings.network,1700,1700 and CH to US915.On the ttn side, I registered the gateway but it says "not connected".Searching on the ttn troubleshooting guide I found the bin file for this Gateway, so I updated the firmware, changed the MAC address to the provided one but no connection.I tried to connect the loriot server with success.I am running out of ideas.Does anybody faced the same or similar problem with ttn? Do anybody have a different bin file or configuration that work with ttn?Thank you.Daniel

Hello,We are using STM32H743ZIT6 revision V.This is connected to an ethernet PHY device via RMII. The PHY outputs the 50MHz RMII REFCLK to drive the RMII on the STM.According to the following sources, the RMII TX data lines (TXD0 and TXD1) should be sampled by the PHY on the rising edge of the REFCLK, and thus should transition around the falling edge:official RMII specSTM32H7 datasheets Table 112. Dynamics characteristics: Ethernet MAC signals for RMIIthe timing diagrams from the PHYThis is not what I am seeing. The STM seems to be transitioning the TX data lines on (or near) the rising edge of REFCLK. We are getting CRC errors detected at the PHY on the RMII interface side.The trace attached shows a packet going out on the RMII. The scope resolution is 2ns, so it's possible the data lines do transition just before the clock edge, but according to the timing diagrams the transition should be at least 2ns before a clock rising edge.Any idea how to solve this? I didn't manage to find a

I'm trying to perform I2C read from external EEPROM upon characteristic value change.I'm able to read from EEPROM before advertisement stage.I'm using sequencer to put char_value_handler in the main thread.But HAL_I2C_Mem_Read() returns HAL_ERROR.The reason is NACK flag is set after writing device & memory address.I've noticed, that if I put a breakpoint before calling HAL_I2C_Mem_Read(), then release it manually everything is OK. The same result is with placing a 0.5 second delay just before HAL_I2C_Mem_Read().I can also put HAL_I2C_Mem_Read() in a while loop and it succeeds on a fourth try.I thought hat it could be some interrupt or hci_event but _disable_irq() makes no change. And no hci_notify_asynch_evt() is called after a HAL_I2C_Mem_Read() call.Maybe I sould use some mutex or status flag before calling HAL_I2C_Mem_Read() but I've already tried everything I could think of.Of course I could proceed with that 0.5 s delay or a while loop but it is so lame.Any ideas what is the r

Hello,I'm testing a custom board implementing a BLE Server. The binary for CPU2 is the stm32wb5x_BLE_Stack_fw 1.3.0. All the radio system seem work well, tested with STM32CubeMonitor-RF and a nucleo dongle (Packet Error Test below 1%). The advertising phase work well too. But when I try to connect a BLE Client, it connects and disconnects immediately after. The reason code of HCI Event is 0x3E (Connection failed to be established).After some investigations, tring to load my firmware on the STM32WB Nucleo Board, I found the problem. I use LSI2 as source clock of RF WAKEUP, this seem not work also on the nucleo board, but switching to LSE (on Cube MX clock configuration), all works well. On my board I can't use the LSE, in reference manual I saw that LSI2 was suitable to source the RF WAKEUP. I already trim the LSI2 with factory value stored at 0x1FFF7548, but the frequency is 30kHz not 32Khz. Could be a problem?It doesn't work also with HSE/1024 as source of RF WAKEUP CLOCKWhy I can't u

Hi,I am using a CAN bootloader to update my application. But after flashing the application and jumping from the bootloader to the reset vector of the app, the program stalls after calling NVIC_EnableIRQ(CAN_TX_IRQn). Is there a problem that the bootloader already used the CAN peripheral?The bootloader resets and stops the peripheral before the jump. Controller is a STM32F303RE.Before NVIC_EnableIRQ is called, the peripheral registers have the following values:MCR = 0x0001004cMSR = 0x00000c00TSR = 0x1c000003RF0R, RF1R = 0IER = 0x00008f03ESR = 0BTR = 0x012d000fUpdate:I looks like the application calls the old interrupt routine address of the bootloader .text.TgtCAN1TXIsr 0x08009be8 0xc VisualGDB/Debug/target.o 0x08009be8 TgtCAN1TXIsr
